lSpecification of Letters Patent..

Application flied september 24.1919. serial No. 325,835.

To all fr0/wm t may concern.'

Be it known that I, CARL GUsTAF SwEBILlUS, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Firearms, of which the following is a speciication.

This invention relates to fire arms and although it is particularly adapted for use in connection with automatic rifles and the like, its utility is not limited thereto.

In my copending application Serial No. 162,543, tiled April 16, 1917, I have disclosed an automatic firearm in which the hammer, hammer spring, trigger and sear are mounted on and'carried by a handle, one end of which is seated in a socket in the rear end of the receiver in alinement with a bore therein in which the breech bolt reciprocates. To remove the breech bolt from the receiver, the handle is disconnected and the breech bolt slipped out through the handle socket.

It is the object of this invention to provide a simple, quiclnacting means for de! tachably connecting a handle of this general character to the receiver of the gun.

To this and other ends the invention consists in the novel features and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, Y

Fig. 1 is a side elevation, partlyY in sec` tion, of an automatic gun embodying` my improved handle-attaching means.

Fig. 2 is a section on line 2 2 of Fig. 1.

Fig. 3 is a detail of the handle.

Fig. 4 is a modified form of the invention.

Referring now to the drawings, the receiver 1 carries at its forward end the barrel 2, and at its rear end the handle 3. Extending longitudinally of the gun are the side plates 4 which enclose the automatic mechanism of the gun. Slidably mounted in the receiver is the breech bolt 5 which operates in the well known manner. In a bore 6 in the handle 3 is mounted a sliding hammer 7 which is urged forward by the spring 8 and normally retained in its rear position by the Sear and trigger 9 and 10 respectively, each of which is pivoted to the handle.

The handle 3 is removably socketed in the opening 11 in the rear end of the receiver,

andris held therein by a special form of latch, shown in detail in Fig. 2. At opposite sides of the rear end of the receiver, are provided slots or kerfs 12 and 13, in which are located the locking plates. 14 and 15 respectively, adaptedv when in the position shown in Fig. 2 to engage vertical grooves 16 in the respective sides of the tubular portion of the handle. One of the platesin this instance, 15-is longitudinally slotted near its outer edge. The arm 16 thus formed is somewhat resilient, for a purpose to be later described and is provided at its free end with a lug or projection 17. rlhe plates 14 and 15 are pivoted to the receiver at 18 and 19 respectively, so that they can swing inward and outward in the slots. rlhe grooves 1 6 come opposite the kerfs and the locking plates when the handle is in the proper position relatively to its socket and in order to lock the handle effectively in place the plates 14 and 15 are swung inward and interconnected by a locking plate 20, pivoted to the plate 14 at 21. and having a notch 22 of 'proper configuration to receive the outer end of plate 15.A To remove the handle, the connecting plate 2O is grasped and pulled upwar'd,the arm 16a yielding to allow the disengagement of the member 20 from the plate 15, and the plates are swung into the releasing positions shown by dotted lines in Fig. 2, whereupon the handle may be freely pulled out of the rear end of the receiver. In assembling the handle with the receiver, the reverse operations are performed, and when the member 20 is forced against the plate 15, the arm 16a yields to allow the end of the plate to seat in the notch 22.

In the modification disclosed in Fig. 4, each of the plates 14 and 15 are provided with notches 23 which are adapted to receive the knobs or the like 24 on the ends of a resilient member 25 carried by the receiver and arranged transversely thereof. The seating of the knobs 24 in the notches 23 serves to hold the plates in position to lock the handle 3 to the receiver 1. c

It is, o f course, understood that while two locking plates are preferred, a single locking plate with means for holding it in position will maintain the handle in its proper position relative to the receiver.

Thus there is provided for attaching the Patented July 1 1, 1922.

handle to the receiver a connecting means which is positive i-nits clamping action but which may be easily released to allow the removal of the handle, together with the hammer, trigger and Sear mounted thereon.

Various changes may be made in the de: tails of the construction, Without departing from the scope of the invention'as defined in the claims.

That I claim is:

l. ln a firearm, a receiver having a slot in the Wall thereof, a* plate pilvoted to swing in said-l slot so that the inner edge of said plate may pass through tlie'slot', a handle member insert-able into' a socket in the receiver and having a groove to register with said! slot and receive' said' plate, and means for holding said platel in locking position*` 2. In a' rearm, a receiver' having kers at oppositeV sides, locking plates pivoted to said receive'r'to swing into and through saifd kerfs, a handle having' grooves to register with said kerfs and receive the inner edges of said plates, and means' for holding' the plates in locking positions.

3. In a firearm, areeeiver having slots in the opposite Walls thereof,- plates piv-V oted to swing in said slots so thatv the inner edges` of said plate ma'7 pass throigh the slots, Va handle member insert'able 'i'ntofa socket in the receiver and having' grooves to register with and receivef said plates, and means for holdingV said plates in locking position. Y Y

4i. In a firearm, a receiver hav-ing slots in the oppositeV Walls'l thereof, plates pivoted` to swin'of .in said slots sof that the'r inner edges o? said plate may passl throughV the slots, a handle member insertable? into a socket in the receiver and having grooves! to register with' andfreceive saidy plates, and meansv carried one' plate adapted to engage the' second plate to holdV said plates in` locking position.

5; In a rearm, a receiver having slots in the opposite Walls thereof, plates pivoted to swing in said slots so that the inner edges of said plate may pass through tl'ieslots, a handle member insertable intof a socket in the receiver and having grooves to register with andY receive said pl-ates, and a member pivoted to one plate adapted to engage the other plate to hold said plates in locking vextending"through the socket Wall, the second member having grooves to register with said slots, pivoted platesv on said first mem;

ber movable in said slots into engagement with said grooves to` lock said members together, and means carried b v one plate adapted to engage' the second Vplate to hold saidl plates in locking position. V

7. n a gun, a ymember having a socket, a second member engaging said socket, the lirst member having'slots in thev socket portion directed transversel7 tothe socket and extending through the socket Wall?, the second member having grooves to register with said slots, pivoted plates on said first memA ber movable in said slots into engagement with said grooves tol lock said members to'- gether, and a member pivoted' to one plate adapted to engage the other plate to hold said plates in locking position.

8'. In a firearm, a receiver havingrl'er'fs at opposite sides, locking plates pivotedr to said receiver to swing into and through said ker'fs, a handle having' grooves to registerV with Said kerfs andreceive the inner edges of saidplat'es, and a memberpivoted to the free end 'of one of sai-dv plates and having a notch in its free end adapted to receive the free end of the' other of sai-dl plates; Y

9'. In a firearm, av receiver having k'erfs at opposite sides, locking plates pi-voted' to;

said receiver to swing into and through said kerfs, one of said plates being longitudinelly slotted, a handle having grooves to register with said kerfs and receive the inner edges of said plates, and afmemb'er pivoted to the unslotted' member and having" a notch at its' free end to receive the free end of said slotted member.v y p CARL SYEBILIUS'
